Deformation Theory of Matrix Factorizations and F-Terms in the Boundary Changing Sector
Johanna Knapp
We extend the deformation theory algorithm of matrix factorizations to systems with more than one D-brane. The obstructions to the deformations are F-term equations which can be in…
Conformal invariance from non-conformal gravity
Krzysztof A. Meissner, Hermann Nicolai
We discuss the conditions under which classically conformally invariant models in four dimensions can arise out of non-conformal (Einstein) gravity. As an `existence proof' that th…
Group field theory renormalization - the 3d case: power counting of divergences
Laurent Freidel, Razvan Gurau, Daniele Oriti
We take the first steps in a systematic study of Group Field Theory renormalization, focusing on the Boulatov model for 3D quantum gravity. We define an algorithm for constructing…
Chaotic Inflation in Supergravity with Heisenberg Symmetry
Stefan Antusch, Mar Bastero-Gil, Koushik Dutta +2
We propose the introduction of a Heisenberg symmetry of the Kahler potential to solve the problems with chaotic inflation in supergravity, as a viable alternative to the use of shi…
Supersymmetric Wilson Loops in Diverse Dimensions
Abhishek Agarwal, Donovan Young
We consider supersymmetric Wilson loops a la Zarembo in planar supersymmetric Yang-Mills theories in diverse dimensions. Using perturbation theory we show that these loops have tri…
The Bethe Ansatz Equations for Reflecting Magnons
W. Galleas
We derive the Bethe Ansatz Equations on the half line for particles interacting through factorized -matrices invariant relative to the centrally extended Lie superalge…
